DMF (dimethyl formamide) waste gas water-washing recycling device and method for manufacturing of copper-clad plates

Abstract

The invention relates to a DMF (dimethyl formamide) waste gas water-washing recycling device for manufacturing of copper-clad plates. The device comprises a filter, a flow meter, a fan, a water-washing tower, a multi-stage circulating water pump, multiple circulating liquid storage tanks and a control system, wherein the filter is connected with the flow meter; the flow meter is connected with the fan; the fan is connected with the water-washing tower; the water-washing tower comprises a wind inlet, a wind-equalizing pore plate, multiple sprayers, a tower plate and a waste gas outlet; the multiple circulating liquid storage tanks are connected with the tower plate; the multiple circulating liquid storage tanks are also connected with the multiple sprayers through the multi-stage circulating water pump; a groove is formed around the outer edge of the tower plate; a circular opening is formed in the middle of the tower plate; the diameter of the circular opening is smaller than that of the inner edge of the groove; multiple rows of flow-guiding inclined plates are supported on the upper end surface of the tower plate; multiple steel plates for fixing the flow-guiding inclined plates are arranged on the upper end surfaces of the flow-guiding inclined plates. The DMF waste gas water-washing recycling device for manufacturing of copper-clad plates makes airflow distribution more uniform, reduces resistance of the tower plate, and adopts multi-stage independent circulating absorption, with the DMF absorbing rate reaching up to 98.5%.

Description

technical field [0001] The invention relates to the technical field of organic solvent waste gas recovery, in particular to a DMF waste gas water washing recovery device and method for manufacturing copper-clad laminates. Background technique [0002] my country is the world's largest producer and exporter of copper clad laminates. During the production of copper clad laminates, a large amount of waste gas containing DMF and acetone organic solvents is discharged, which not only pollutes the environment but also wastes valuable resources and increases production costs. There are also hidden safety hazards in production. The organic waste gas treatment of CCL has become an important factor restricting the survival and development of this industry. [0003] The traditional CCL organic solvent waste gas treatment generally adopts the combustion method and the latest honeycomb rotary concentration adsorption-catalytic combustion method. Among them, although the combustion m...
